The RFS2 establishes several categories of advanced biofuel. An advanced biofuel (except ethanol) can be made from corn starch if it achieves a 50% reduction of GHG emissions vs. gasoline. Cellulosic biofuels must achieve a 60% reduction. Gevos isobutanol from retrofit ethanol plants may ualify as an advanced biofuel if it meets the 50% GHG reduction.
